It is not easy to negotiate the conditions when exchanging the future for immediate benefits.

For Mizuki, being able to promise to change one is already doing his duty to Grandma Chiyo. If she is really unscrupulous, it would be fine to agree to it.

After the Fourth Shinobi World War, thorny issues like the Tailed Beasts will most likely be left unresolved, with no need for Mizuki to interfere.

Granny Chiyo's worries were actually groundless, but Mizuki couldn't convince her with things that hadn't happened. Granny Chiyo now only had the interests of Gaara and the Sand Village in her eyes, so he had to ask him to change to someone more reliable.

"Let's talk about it first!"

Mizuki saw that Grandma Chiyo seemed to want to make some conditions, so he spoke first.

"This is my private behavior. It has nothing to do with Konoha Village. I don't have the power to do much. I can only use my personal name as a bargaining chip!"

Even if Mizuki became the Hokage, he would not exchange the interests of the village for personal gain. The public and private must be clearly distinguished.

"Don't worry, my conditions will definitely not make things difficult for you."

Grandma Chiyo giggled without caring about her image, and then spoke.

"I want a secret method of training to stabilize my spirit. I'm sure Mizuki Jonin will understand. This should be your personal secret technique and has nothing to do with Konoha Village. Can it be used as a condition for exchange?"

"I see, it seems like I'm at a disadvantage!"

Mizuki was a little hesitant. Any kind of secret technique that could enhance the spiritual side was a rare skill. As long as one mastered the trick, it would be an heirloom that could support a large ninja family and benefit future generations. It didn't seem worth it to just exchange for one's own reincarnation.

"Excuse me, what do you want to do with this?"

The Sand Village's overly eager and pragmatic way of training ninjas makes it difficult for them to make achievements in illusion, spiritual secret techniques, and other hidden techniques. They do not have enough resources like Konoha to be inclusive.

The only thing that involves this aspect is puppetry. Through certain deliberate means, similar mental attacks can also be achieved.

For example, during the Chunin Exam three years ago, there appeared a pair of Genin sisters from the Sand Village who had special mental abilities. However, that was only because they were born with strong mental powers, and then used puppetry on the enemy to achieve the effect of Yin-attribute ninjutsu in disguise. But this kind of genius is hard to come by.

In Konoha Village, everyone knows that the Eight Gates of Ninjutsu is very powerful. Before opening the last few gates, although it is dangerous, it is actually a very cost-effective forbidden book of physical techniques.

But in fact, besides Might Guy and Rock Lee, only Hatake Kakashi was able to learn it. Other ninjas simply did not have such talent.

It takes only one ninja every ten to twenty years to be able to withstand the harsh training of practicing the Eight Gates Ninjutsu and be willing to develop in this direction. There are too few of them.

"It seems that there is no way to complete the transaction without allaying the doubts in Mizuki Jonin's heart."

Chiyo said after thinking for a moment.

"Although there are fewer talents in the Sealing Technique in the Sand Village now, it was not like this before..."

Without sufficient strength, how could he have sealed the One-Tail Shukaku before the First Hokage of Konoha Village, Hashirama Senju, and Madara Uchiha established the order of the Ninja World?

"The sealing skills of the Wind Country are too eccentric, I'm sure you know that!"

Mizuki nodded.

The Kingdom of Wind is a poor country with many kinds of beliefs spread throughout the country and there are also many temples of all sizes. These semi-religious, semi-secular organizations are able to survive in the world because most of them have special skills. They are good at chakra combat training, and the monks who attach great importance to the cultivation of the mind have a good inheritance in the art of sealing.

Unfortunately, most of these guys are not interested in how to seal perfectly, but are particularly good at removing the seal. This is particularly embarrassing for the Sand Village.

"The Sand Village has only had two One-Tailed Jinchuriki so far. The previous Jinchuriki, Bunfuku, was a highly respected monk who had been sealing himself for decades in order to seal the One-Tailed Shukaku. But a monk like Bunfuku is so rare that it is difficult to find one, so the One-Tailed Jinchuriki Gaara appeared. Although it was Rasa who insisted on his own way back then, I also acquiesced, which led to the tragedy later..."

Chiyo, who was a little tired, took a breath and then continued.

"The seal used by the Sand Village to seal the One-Tailed Shukaku is a psychic seal. This seal is not very powerful, but it is very resilient. It is perfect for a tailed beast like the One-Tailed Shukaku, whose chakra has sealing properties and is particularly difficult to be suppressed by a Jinchūriki."

If the Eight Trigrams Seal that the Fourth Hokage Minato Namikaze formed by using two Four Symbols Seals was like a solid wall of iron, then the Psychic Seal was like a thick rubber cage.

As long as the One-Tail Shukaku cannot completely break the psychic seal in an instant, it will be difficult for it to get out. This can greatly alleviate the danger of the One-Tail Shukaku breaking the seal and getting out.

But there is another problem here, which is that the mental pressure on the One-Tail Jinchuriki is simply too great.

Ever since becoming the One-Tailed Jinchuriki, Gaara has hardly even dared to sleep, for fear that the One-Tailed Shukaku's power would leak out and use his body to kill people indiscriminately.

“So, I wanted a solution to this dilemma.”

The Sand Village will definitely not give up Shukaku, the one-tailed beast, but as long as such a flaw exists, another tragedy will happen sooner or later.

Although it is difficult to find people with excellent physical fitness, it does exist. However, it is really rare to find people with strong mental strength at the same time.

"I think I understand what you want."

Mizuki nodded. This condition was not complicated. However, it was a bit greedy to want to use one's own reincarnation to get the results of Mizuki's research for so many years. After thinking for a while, Mizuki took out the storage scroll, took out a strange red thing, and handed it to Kankuro beside him.

"Here, we are even."

"What's this?"

Kankuro took it and turned it over and over again, unable to understand it.

This thing is like an elongated cross heavy sword, but it has no blade. The tip of the sword is a bit sharp, so it should have good lethality.

"Insert it into the ground, anywhere, and then the user will infuse chakra into it, and it will form a barrier of nearly ten square meters in radius, protecting the spirit of the person inside from harm. It also has the effect of soothing mental fluctuations and strengthening mental strength."

The effect is similar to an enhanced version of the concentration technique, and is similar to the scroll that Mizuki gave to Haruno Sakura to assist in her practice, except that the effect is better and more comprehensive, and it is also more durable.
